After IAP integration, you must check the operation mode before submitting the app. If you submit the app with OPERATION_MODE_TEST, licensed users continue to get all the items for free but all other users see an error message if they try to purchase an item. So, before beta release or normal publication, confirm that the operation mode is OPERATION_MODE_PRODUCTION.
Before submitting your app and its in-app items for review testing and normal publication in the Galaxy Store, you can beta release a test version of the app and one or more of its items to test IAP integration.
All beta testers download the beta app from the beta test URL for free (including paid apps). Beta testers can be non-licensed (must be billed for in-app item purchases) or licensed (get in-app items for free).
For successful beta testing, beta testers need to uninstall the existing app and install the app using the beta test URL.
If you make modifications to your app during a beta test, you must update the app in Seller Portal and then beta release this app. Beta testers must uninstall the old beta version and use the new beta test URL to download the new beta version.
